I bought this guide at the airport in December 2010, while leaving for the Yucatan peninsula. I was attracted by the title. I thought: “2011, wow that guide must have the very latest!”. Well, I was terribly wrong.
There is just to much in this guide that is completely outdated. And not by just a few months.

Take Chichen Itza, one of the most popular Mayan sites in Yucatan (and a superb one, by the way). The book says an access to see the inside of the “Castillo” is open 11 am – 3 pm. But our the local person who guided us during 3 unforgettable hours on site showed us the closed door… and said public was not permitted inside the pyramid since more than a year. Tulum, another breathtaking Mayan city by the Caribbean: the book gives the price of hiring a local guide. They are wrong by a factor 3! And these are very, very popular destinations. You’d think they’d at least do a good job writing about these.
When it came to the less touristy bay we were staying at, north of Tulum, there again: there was information that was way wrong.
I will soon be back to Mexico, this time in Mexico City and I hope the guide is more worthy this time. I may go up to 3 stars. But for Yucatan, it only deserves 2.

A good quick reference if you’ll only be in each town of Mexico for a day or 2. Not much in-depth info. I was on a cruise ship in the Mexican Riviera and this was just enough info to last a day. If making an extensive trip through Mexico, I would recommend another book.
